The APstorage Lake-6 is an integrated, plug-in AC-coupled energy storage system designed to make residential energy storage simpler and more accessible. It combines a 6.02 kWh LiFePO4 battery and intelligent power conversion technology in one streamlined unit.

Designed to integrate with existing residential PV systems, Lake-6 stores excess solar energy for use when it is needed most. With up to 2,500 VA of continuous input and output power, up to 3,600 VA of peak backup power and rapid 5-millisecond switching, Lake-6 helps homeowners increase solar self-consumption, manage energy costs and keep essential household loads powered during an outage.

Everything Home Energy Storage Needs in One System

Lake-6 combines battery storage, intelligent power conversion and energy management in one integrated solution. Its AC-coupled design makes it a flexible option for adding storage to an existing residential solar system without replacing the current PV inverter.

The integrated 6.02 kWh battery stores excess solar production for use after sunset, during periods of higher electricity rates or when the grid goes down. One-click controls and intelligent operating modes make it easier to manage energy around the household’s individual needs.

Broad PV Compatibility

Designed to integrate with existing residential PV systems, Lake-6 adds storage without replacing your current inverter.

AI-Powered Optimization

Built-in AI intelligently manages battery charging and discharging based on your household’s real energy usage patterns.

Long Battery Lifespan

Rated for more than 8,000 cycles at 25°C with a 90% depth of discharge, Lake-6 is built for years of dependable daily use.

Real-Time App Monitoring

Track performance, manage settings and receive real-time updates from anywhere using the AP EasyPower app.

Ideal for Every Household

A compact, plug-in design and 6.02 kWh of usable storage make Lake-6 a flexible fit for a wide range of homes.

Multi-Layer Safety Protection

An IP65-rated enclosure and multiple layers of protection keep the system safe across a wide range of installation environments.

Plug-and-Play Installation

The AC-coupled, plug-in design keeps installation simple, without complex rewiring of your existing solar system.

Zero-Export Capability

Pairs with a smart meter to help households meet zero-export requirements and avoid sending power back to the grid.

Ultra-Quiet Operation

Operating below 20 dB, Lake-6 runs quietly enough for installation close to living spaces.

VPP-Ready Design

Built-in compatibility with virtual power plant programs lets households participate in grid support initiatives.
